Casting a tab or entire desktop

Why watch you favorite entertainment or browse the internet on your desktop when you can enjoy it on big screen? By casting a Chrome browser tab, you can mirror what's displaying on your computer screen onto the TV. To get started, be sure you're fully set up to use Chromecast with Chrome.

Set up casting from Chrome

  1. If you're not already running Chrome, download Chrome. 
  2. Ensure you're running the latest version of Chrome. If you're having trouble, here's how to get Chrome updates.
  3. Though not required, we recommend you pin the Cast button to your Chrome toolbar.
  4. If you plan to cast a tab to your Chromecast to watch video on TV, review the Minimum System Requirements to ensure that your computer and network are capable of supporting this.
  5. Make sure your laptop/computer is connected to the same Wi-Fi network as your Chromecast device.

How to know when content is casting

The Cast button will automatically appear in your Chrome toolbar and turn blue  Inactive cast extension when it’s active. You'll also see a glow around the icon of the tab being cast.

What can be cast

You can cast the majority of web content. Sites using plug-ins like Silverlight, Quicktime & VLC aren’t supported and may result in a lack of picture or sound.

Audio and video

You’ll see video and images for the selected tab on your computer and TV. However, you’ll only hear sound from the selected tab on your TV. Note: Sounds for other tabs and applications will continue to play on your computer.

If my Chromecast is currently in use

After opening the menu or selecting the device, you’ll see a short description of Chromecast’s current activity. Click the Cast this Tab button to stop what’s showing and cast the current tab instead.

Shortcuts available

  • Switch to other tabs and/or applications while casting using the Alt-Tab (Mac: Command-Tab) keyboard shortcut.
  • Close the Cast dialog to return to the original tab.
  • Mute what’s casting to your TV by clicking the mute button. Note: This is distinct from your TV's mute function. You need to unmute from Chrome to hear sound on your TV.
